Dodge Challenger SRT Hellcat is the most powerful muscle car ever at 707hp

The all-new 2015 Dodge Challenger SRT, with its supercharged 6.2-liter HEMI® Hellcat engine, produces an unprecedented 707 horsepower and 650 lb.-ft. of torque, making it the most powerful Challenger ever, Dodge's most powerful V8 ever and the most powerful muscle car ever.

The Challenger's new 6.2-liter Supercharged Hellcat engine is also the first factory supercharged HEMI, as well as Dodge and SRT's first application of V8 supercharger technology. For the first time in Chrysler Group history, the all-new 2015 Dodge Challenger SRT with a Hellcat engine comes standard with two key fobs -- red and black. The red key fob is the only key that can unlock the full 707 horsepower and torque potential of the Challenger SRT Hellcat engine; while the black key fob limits the driver to a reduced engine output of 500 horsepower.

In addition to the awe-inspiring 707 horsepower of the new Hellcat HEMI, the new 2015 Dodge Challenger SRT Hellcat has been redesigned and totally re-engineered to be the most true-to-form muscle coupe on the market with performance-enhancing technologies inside and out, including the new TorqueFlite eight-speed automatic transmission and an all-new interior inspired by the classic 1971 Challenger.

The Dodge and SRT brands now offer the most complete lineup of muscle cars in the market, including the new 2015 Dodge Challenger SXT with its standard powerful and fuel-efficient Pentastar V-6 engine combined with the TorqueFlite eight-speed transmission that delivers 300 horsepower and an estimated 30 miles per gallon; the 2015 Dodge Challenger R/T with the high-torque 5.7-liter HEMI now paired with the TorqueFlite eight-speed or six-speed manual transmission; and the all-new 6.4-liter HEMI Challenger Scat Pack that delivers 485 horsepower and 475 lb.-ft. of torque with the TorqueFlite eight-speed or six-speed manual.

The 2015 Dodge Challenger and Challenger SRTs are built at the Brampton, Ontario, assembly plant and will start arriving in Dodge dealerships in the third quarter of 2014.
